Sustainable development is a concept that focuses on meeting the needs of the present generation without compromising the ability of future generations to meet their own needs. It incorporates three key aspects:
1. Economic growth: Ensuring long-term economic stability and growth while maintaining the efficient use of resources.
2. Environmental protection: Preserving biodiversity, ecosystems, and reducing pollution to maintain a healthy planet.
3. Social equity: Addressing social inequalities, providing equal opportunities, and creating access to basic services such as education and healthcare.
Sustainable development aims to strike a balance between economic progress, environmental sustainability, and social well-being to ensure a harmonious coexistence for all.
In the adjoining figure, \( AP = 1 \, \text{cm}, \ BP = 2 \, \text{cm}, \ AQ = 1.5 \, \text{cm}, \ AC = 4.5 \, \text{cm} \) Prove that \( \triangle APQ \sim \triangle ABC \).
Hence, find the length of \( PQ \), if \( BC = 3.6 \, \text{cm} \).
